Abstract

The volatile oil from Zanthoxylum bungeanum Maxim. cv. Dahongpao has been associated with various pharmacological activities. A systematic method was used to optimize the supercritical carboon dioxide extraction (SCDE) of the volatile oil. Overall 3 variables (pressure, temperature, extracting time) were considered. The optimized conditions were: temperature 55 ℃, pressure 33 MPa, time 60 min. Thirty one chemical components of the volatile oil were determined qualitatively and quantitatively by GC-MS. Among them the content of 3 methyl-2- ozafluorene is the highest, about 18.63 % .
